Begins by defining which red, green, and blue wavelengths are required for the proper hue blending, determining an appropriate Bandwidth, and processing to attain this while maintaining sufficient diffraction efficiency. Procedure is outlined for the multiple exposure of a color reflection hologram that contains the three primarys. Where two primarys overlay producing the secondary hues and attaining a "White" where all three primarys overlay. The resulting hues are analyzed on a spectrometer.
